Yeah your talking similar money to TE37SL's, maybe a little more due to the rarity. They are basically a 5 spoke version of the TE37, both made by Rays.
I have just complete my set of TE37's, x2 18x9.5's for the front and x4 18x10.5's for the rear. So lightweight, look forward to getting them on.
Mayes SSR is another good manufacturer, make some great looking Motorsport wheels too.
